INVENTOR ATTORNEYS SES! f JOHN o. LYoNs, or Mccoivng, `1vIISsISsI1 rI REINFOCED LOCOMOTIVE-DRIVINGr-BOX SHOE.

To all whom t may concern ABe it known that I, JOHN C. LroNs, a citizen 4of the United States, and a resident of McComb, in the county of Pike and State of Mississippi, have invented certain new and useful Improvements in Reinforced Locomotve-Driving-Box Shoes, of which the following is a speciication.

My invention is an improvement in reinl forced locomotive driving box shoes, and the invention has for its object to provide a shoe of the character specified, wherein steel reinforcing plates are cast' in the shoe, to strengthen and reinforce the same, to prevent damage in use. j

In the drawings: Figure 1 is a partial side view of a locomotive provided with the improved shoes; Fig. 2 is a front view of one of the shoes; Fig. 3 is a longitudinal section of Fig. 2; Fig. 4 is a front view of the othershoe; Fig. 5 is a longitudinal section of'Fig. 4, and Fig. 6 is a section on the line 6 6 of Fig. 4.

The present embodiment of the invention is shown in connection with 'the frame 1 of a locomotive, the said frame having a vertical recess or passage 2, in which is arranged the driving box 3, and the shoes to be described are arranged at opposite sides of the recess or passage for engagement by the grooved edges of the driving box 3.

The shaft 4 of the drive wheels 5 is held in the driving box, and the box is mounted for vertical movement in the passage. These shoes, shown yin detailin Figs. 2 to 46 inclusive, are cast as a rule from iron, and

both shoes are channel-shaped, the one shoe or wedge comprising a body 6, and side walls 7 and the said body is 'of less thickness at its top, gradually increasing in thickness toward the bottom, as shown, while the side walls have their free side' edges parallel and in the same-plane. At its lower end the shoe 6 7 has an undercut notch or recess 8, for receiving adjusting mechanism in the form of a headed rod 9. This rod is threaded through the fra-me, as shown, and the head of the rod engages the undercut notch 8, and lock nuts 10 are arranged on opposite sides oi' a bearing clip 11 on the frame through which the rod passes. The rod is threaded as shown, and the shoe may be adjusted by turning the rod 9.

The shoe shown in Figs. 4 to 6 inclusive .comprises a body 12 and side walls 13, and

the body 12 is of the same thickness throughout its length. This shoe 12 13 is arranged at the opposite side of the recess or passage 12 from the 'shoe 6 7, and the side walls of the recess fit in the channels of the shoes, while the fianges of the bearing box 3 engage the sides ofthe shoes.

Each shoe is reinforced by substantially U-shaped steel plates, each consisting' of a body 14 and arms 15 extending at approximately a right angle with respect to the body.o Each shoe is provided with threel of the plates 14 -15, and the bodies ofthe plates are arranged transverselyof the bodies of the shoe, with the arms 15 of the plates in the side walls 7 and 13 of the shoe. In the shoe 6 7 the bodies 14 of the plates are arranged near. the inclined innerl face of the body 6 of the plate, and in the shoe 'through the openings 16 to form ties for preventing relative movement of the plate and the shoe and to make the structure practically integral. As shown, ve openings 16 are provided in the body of each plate, and two openings in each arm of each plate.- The free ends of the arms 15 of each plate are flush with the free edge of the adjacentside wall, and the plates are hidden and concealed within the bodies of the shoes. The openings are omitted at the connections between the bodies and the arms of the plates, in order to preserve the full strength of the plates at this point.

I claim:

1. A locomotive driving box shoe of channel shape and composed of cast metal, and comprising a body and side walls extending laterally from the body, a series of reinforcing plates of steel embedded in the material of the shoe, said plates each comprising a body arranged transversely of the body of the shoe, and arms extending laterally from the body and embedded in the side walls of the shoe, said plates being arranged at the and having transverse openings to permit the passage offthe material of the shoe through the openings, the free ends of the shoe through the'openings.

Copies of this patent may-be obtained for from the body and embedded in the side walls of the shoe, said plates being arranged at Athe ends and intermediate the ends of the shoe and having transverse openings to permit the passage of the material o/the 3. A locomotive driving box shoe of channel shape5and composed of east metal, and comprising a body and side Walls extending laterally from the body, a series of reinforcing plates of steel embedded in the material of the shoe7 said plates each comprising a body arranged transversely of the body of the shoe, and arms extending' laterally from the body and embedded in the side the shoe.

el. A locomotive driving box shoe of chan'- nelshape and composed'of east metal, and composed of a body and side walls extending laterally from the body and a reinforcing plate of steel embedded in the material of /tlie shoe` each plate comprising a body arranged transversely of the body of the shoe, and arms extending laterally from the bodyl and embeddedin the side walls of the shoe.
